Problems solved by technology

However, manually reconfiguring the physical interconnection is extremely complicated, and requires a large number of working processes.
The core switch capable of full-mesh connection is expensive, and in case of a high-speed network interface, a core switch having a large scale full-mesh connection becomes more expensive.
Furthermore, in association with increasing transmission rate, distortion or loss of a signal in the core switch or interference between signals occurs, thereby restricting the number of ports in which full-mesh connection is possible.
Thus, cost of the network system increases.

Embodiment Construction

[0044] Exemplary embodiments of the present invention are explained in detail below with reference to the accompanying drawings.

[0045] A configuration of a network system and change in a network topology according to one embodiment of the present invention are explained first with reference to FIG. 1A to FIG. 1C. FIG. 1A is a first diagram for explaining the configuration of the network system and the change in the network topology according to one embodiment of the present invention.

[0046] As shown in FIG. 1A, the network system includes a physical-interconnection selection switch 10 having slower switching speed and lower cost as compared with those of a core switch; middle switches 1 to 7; and a controller 100. For convenience of explanation, seven units of middle switches are shown in FIG. 1A, but the network system can be configured with an arbitrary number of middle switches. Furthermore, the physical-interconnection selection switch 10 may be an electrical switch or an opti...

Abstract

In a network, a controller controls a physical-interconnection selection switch and middle switches so as to dynamically change a network topology according to the state of the network. A traffic analyzer detects how the traffic in the network changes. If there is a change in traffic, the controller controls the physical-interconnection selection switch and the middle switches so as to change the network topology to one suitable for the changed traffic.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a device and method for network configuration and a computer product for allowing easy and low-cost operation control of a network system. [0003] 2. Description of the Related Art [0004] In conventional network systems, network configuration can be changed by manually reconfiguring physical interconnection according to a request for changing a network. However, manually reconfiguring the physical interconnection is extremely complicated, and requires a large number of working processes. Therefore, a core switch with which full-mesh connection is possible is installed in the center of the network system, to centrally control the network (such as reconfiguring of a virtual local area network (VLAN)), and to construct a network system capable of dealing with a change request for a network (for example, see “Catalyst 6500 series”, Searched on Sep. 15, 2005.
